India Pale Ale is a beer characterized by a light color and strong hoppy flavor. About six different styles of pale ales exist, including the IPA. The nutritional values of IPAs vary depending on the manufacturer, ingredients and brewing process. Double and triple IPAs have much higher malt and hop contents than regular IPAs and, as such, typically have greater carbohydrate and alcohol contents.

IPAs generally contain a large amount of pale hops, fermented with yeast and barley malt. Brewers typically add a sugar solution in the later stages of the fermenting process as well. Hops and brewer's yeast are natural plant products and provide a rich source of vitamins and minerals. The yeast content in beer contributes a small dose of protein -- an IPA has about 2 grams of this nutrient.
An IPA's caloric value is fairly consistent with other styles of beer; it generally contains between 180 to 200 calories per 12-ounce bottle. Sam Adams IPA has one of the lowest calorie totals, with 175 per bottle, while Sierra Nevada's IPA contains one of the highest, with 231. A typical bottle of IPA accounts for about 9 percent to 10 percent of the daily calorie intake, based on a 2,000-calorie diet.
Most beers contain a large amount of carbohydrates. Because of their greater quantity of hops, IPAs have more carbohydrates than the average beer. While pale ales contain about 10 to 14 grams of carbohydrates, IPAs can have up to 20 grams or more per 12-ounce bottle. Healthy adults generally need about 225 to 325 grams of carbohydrates each day.
The greater hop content in an IPA leads to a stronger fermentation, so IPAs generally have a higher alcohol content by volume than the average beer. Pale ales have about 5 percent to 6 percent alcohol content by volume, while IPAs have about 6 percent to 7 percent.
